IFNγ: Issuing macrophages a license to kill
نویسنده
چکیده
T cells tell macrophages when to start making the toxic soup of lysosomal enzymes, reactive oxygen species, and nitric oxide that destroys intracellular pathogens. In 1983, Carl Nathan proved that this start signal comes in the form of the secreted cytokine IFNgamma.

background: Classical macrophages (M1) and alternative macrophages (M2) are responsible for various functions in order to maintain homeostasis. BCG vaccine and hydatid cyst fluid can be examples of stimulants which can cause M1and M2 macrophage polarization. Evaluating the expression of markers such as IFNγ and TNFα for M1 phenotype and TGFβ and IL4 for M2 phenotype is one of the confirmatory w...

Legionella pneumophila is the causative agent of Legionnaires' disease, a potentially fatal lung infection. Alveolar macrophages support intracellular replication of L. pneumophila, however the contributions of other immune cell types to bacterial killing during infection are unclear. Here, we used recently described methods to characterise the major inflammatory cells in lung after acute respi...

Introduction Antitumor immunotherapy is aimed at stimulating specific and/or nonspecific immunity, resulting in the activation of T-cells, B-cells, macrophages and NK cells to kill tumor cells. Nonspecific immunity, using cytokines such as IL-2, IL-12, GM-CSF and IFNγ tends to stimulate the global immune system to amplify a potential antitumor immune response. IL-2or IFNγ-based therapies are co...
متن کاملUnderstanding the influence of the tumor microenvironment on macrophage responses to CD40 agonists
Both TH1 and TH2 cytokines influence the antitumor functions of macrophages. We have recently shown that interferon γ (IFNγ) licenses the antineoplastic functions of CD40 ligand (CD40L)-stimulated macrophages more efficiently than interleukin (IL)-4 and IL-13. The presence of a TH1 and TH2 skewed tumor microenvironment may therefore influence therapeutic responses to CD40 agonists, agents that ...
